Rate Law - Practice Questions & MCQ

Consider the reaction, products. When concentration of alone was doubled, the half­-life did not change. When the concentration of alone was doubled, the rate increased by two times. The unit of rate constant for this reaction is

The rate law for a reaction between the substances A and B  is given by rate =  

On doubling the concentration of A and halving the concentration of B, the ratio of the new rate to the earlier rate of the reaction will be as

In a reaction, A + B Product, the rate is doubled when the concentration of B is doubled, and the rate increases by a factor of 8 when the concentrations of both the reactants (A and B) are doubled, rate law for the reaction can be written as :

For the reaction it is observed that:

1. On doubling the initial concentration of A only, the rate of reaction is also doubled and
2. On doubling the initial concentrations of both A and B, there is a change by a factor of 8 in the rate of the reaction.

The rate of this reaction is given by:

 For the reaction,  the differential rate law can be written as :

For a reaction between A and B, the order with respect to A is 2 and the order with respect to B is 3. The concentrations of both A and B are doubled, the rate will increase by a factor of:

Consider the reaction
